high-side drive by P-mos

To use a P-channel MOSFET (P-MOS), you should use it as a high-side switch.

Explanation:

• A P-MOS turns ON when its gate voltage is lower than its source voltage (typically, gate pulled to ground or a lower voltage).
• In a high-side configuration, the source is connected to the positive supply (Vcc), and the drain connects to the load.
• When you pull the gate low, the P-MOS conducts, allowing current to flow from Vcc through the load to ground.

Low-side drive is typically used with N-channel MOSFETs, not P-channel.
